The lamp 42 may be accommodated in the case 41, so that it is possible to prevent the lamp 42 from being excessively exposed to oil fume to be affected with moisture, and to prevent the lamp 42 from being damaged. It can be understood that the box 41 has a certain shielding effect on the ultraviolet rays emitted from the lamp 42, and then in order to avoid the reduction of the cleaning efficiency of the lamp 42, an opening 410 needs to be formed on the box 41 to expose the lamp 42, so that the ultraviolet rays emitted from the lamp 42 can disinfect and decompose the primarily filtered oil smoke. The opening 410 may be formed on the top of the case 41, or may be formed on the side of the case 41, and the specific forming position of the opening 410 on the case 41 is not limited in this application.

Referring to fig. 5, in some embodiments, the number of the lamps 42 may be multiple, and the multiple lamps 42 may be disposed at intervals. Thus, by providing a plurality of lamps 42, the ultraviolet radiation efficiency can be enhanced, thereby increasing the oil fume decomposition rate.

Specifically, the number of the lamp tubes 42 may be determined according to the size of the air purifying apparatus 1000, and it is understood that the lamp tubes 42 are arranged as double tubes, which has higher power and stronger sterilization effect than the lamp tubes 42 arranged as single tubes. In the present embodiment, the lamps 42 are double tubes, and two lamps 42 are disposed at intervals and accommodated in the box 41 and exposed through the opening 410 to release ultraviolet rays to the installation space 14, so as to decompose and sterilize the cooking fume.

In one embodiment, the operation of the air purification apparatus 1000 in the present application is substantially as follows: the air purification device 1000 is powered on, the power controller 500 starts to work, the switch device 600 is controlled to work, the fan 300 is started, and the ultraviolet device 400 is started at the same time, so that the fan 300 sucks oil smoke into the shell 100 after oil and fat separation through the filter screen 200, then the ultraviolet device 400 sterilizes the oil smoke passing through the inside of the fan 300, and then the oil smoke is discharged to the indoor or outdoor space from the air outlet 16.
